Maps shading terrain as if illuminated by a point light source (i.e. hill-shading) are commonly used in cartographic displays. These hill-shaded maps are especially important for representing mountainous areas, due to the rapid variations in the orientation of terrain elements. Although these hill-shaded maps reveal the coarser landforms and the finer texture of the terrain, they can be enhance...

In this paper, several models are integrated into a thermal model to study the impact of occupants’ behaviors on the building energy consumption. An air flow model is developed to simulate ventilation related to the occupant’s patterns of window opening and closing. An electric consumption model is developed to simulate the usage pattern and the electricity input to household electric appliance...

An image is composed by several intrinsic images including the reflectance and the shading. In this paper, we propose a novel approach to infer the shading image from shading orders between pairs of pixels. The pairwise shading orders are measured by two types of methods: the brightness order and the low-order fittings of local shading field. The brightness order is a non-local measure, which d...

When rendering effects such as motion blur and defocus blur, shading can become very expensive if done in a naïve way, i.e. shading each visibility sample. To improve performance, previous work often decouple shading from visibility sampling using shader caching algorithms. We present a novel technique for reusing shading in a stochastic rasterizer. Shading is computed hierarchically and sparse...

Shading has a great impact to the human perception of 3D objects. Thus, in order to create or to deform a 3D object, it seems natural to manipulate its perceived shading. This paper presents a new solution for the software implementation of this idea. Our approach is based on the ability of a user to coarsely draw a shading, under different lighting directions. With this intuitive process, user...

Quite a few techniques have been proposed on how to implement more complex and realistic shading models with graphics hardware [5, 7], making them useful for VR applications. Still, these techniques are rarely used, probably due to two reasons: complex implementation issues, and unintuitive parameters for the used shading models. We propose to use a simple technique called "NDF shading". It all...

This work reconstructs 3D graphics model of an object from an image sequence taken during the object rotation. Shading and its motion information are used in estimating shapes of smooth surfaces between fixed edges from corners and patterns. Being different from conventional shape from shadings that use one or several images, we use an image sequence that provides not only shading but also its ...

The results of two year studies (2003 − 2004) were presented, concerning the effect of various manners of ‘Tango’ celery shading on NR activity and the contents of NO3 and NH4 ions, free amino acids, soluble sugars and dry matter, all of which were determined in the stalks and blades of leaves on three different dates, including the harvest time. Three different shading types were used: shading...

This paper proposes a new configuration for solar energy conversion systems. One challenging issue of the photovoltaic (PV) systems is partial shading, and in this paper Module Integrated Converters (MIC) are used to overcome this problem in PV arrays. A few boost converters are employed as MICs to mitigate the shading effect. Furthermore, to reduce the cost and to increase the system performan...

A set of algorithms is proposed in this paper to automatically transform 3D animal models to Chinese painting style. Inspired by real painting process in Chinese painting of animals, we divide the whole rendering process into two parts: borderline stroke making and interior shading. In borderline stroke making process we first find 3D model silhouettes in real-time depending on the viewing dire...
